<h3>Import ACE30 DEM Tile</h3>


<p>Imports a tile of the ACE&nbsp;elevation model&nbsp;at 30 arc second resolution referenced to the EGM96 geoid.</p>

<p>
    See ACE Report at <a href="http://www.cse.dmu.ac.uk/geomatics/products_ace_overview.html">http://www.cse.dmu.ac.uk/geomatics/products_ace_overview.html</a>
</p>

<p>Since
    the ACE height information is referred to geoid EGM96, not&nbsp;WGS84
    ellipsoid,&nbsp;correction has been applied to obtain height
    relative to the WGS84 ellipsoid.&nbsp;</p></body>
